LONDON — The World Health Organization will start large-scale testing of an experimental Ebola vaccine in Guinea on Saturday to see how effective it might be in preventing future outbreaks of the deadly virus.

LONDON — British lawmakers will vote Tuesday on whether to let scientists use controversial techniques to create babies from the DNA of three people — a move that could prevent children from inheriting potentially fatal diseases yet would make Britain the first country in the world to allow embryos to be genetically modified.

LONDON — New rules proposed in Britain would make it the first country to allow embryos to be made from the DNA of three people in order to prevent mothers from passing on potentially fatal genetic diseases to their babies.
In a statement issued on Wednesday, the department of health said it had taken "extensive advice" on the safety and efficacy of the proposed techniques from the scientific community.

LONDON - Scientists say there is "overwhelming evidence" that a skeleton found under a parking lot is that of England's King Richard III, but their DNA testing also has raised questions about the nobility of some of his royal successors.

LONDON — Two months ago, the World Health Organization launched an ambitious plan to stop the deadly Ebola outbreak in West Africa, aiming to isolate 70 percent of the sick and safely bury 70 percent of the victims in the three hardest-hit countries — Guinea, Liberia and Sierra Leone — by Dec. 1.
Only Guinea is on track to meet the Dec. 1 goal, according to an update from WHO.
